The body was taken by helicopter to the Coconino County Medical Examiner's Office, which will confirm the identification, according to reports.

Mark McOmie, Standefer's uncle, said in a Facebook post that the family is waiting to comment until the body is formally identified.

Standefer and his grandmother LouAnn Merrell, 62, went missing in the Arizona park on April 15. Merrell has still not been found.

Merrell, the wife of famed boot-maker Randy Merrell, was on a multi-day hike with her stepgrandson and the boy’s mother when she and the boy lost their footing while crossing a creek and were swept away by water.

Search teams combed the area by land, water, and air, but last week the search was scaled back.

Authorities found Standefer’s backpack, which had a GoPro attached to it, during the search last week.
